Tunable antenna circuit, essentially characterized in that it comprises an insulating support, provided with fixing means to a support surface and two pairs of symmetrical guide devices with respect to a vertical axis and comprising two mouths directed parallel upwards and two mouths directed diverging towards opposite sides, in whose guide devices are mounted separate elastic strips, conductors and tending to stay in a rectilinear position, each of them projecting and sliding in the mouths of each pair, with their ends joined, by a part in common to an insulating piece that connects the two parallel branches that project upwards from the upper mouths, and, on the other, to two fixed points of the insulating piece forming respective loops, so that the displacement of the straps determines variations complementary in the lengths of the vertical branches and of the loops.
